It is tempting to use Jamse's patch because the code does get more elegant. On the other hand the suggestion to develope pivotal to twisted makes a lot of sense too. I Hope this patch will become part of twisted soon. Thanks to bob for showing me the "conventional" way of doing it. I just tested his code and it works on my setup too. _stephan -- +++ GMX - die erste Adresse für Mail, Message, More! +++ Getestet von Stiftung Warentest: GMX FreeMail (GUT), GMX ProMail (GUT) (Heft 9/03 - 23 e-mail-Tarife: 6 gut, 12 befriedigend, 5 ausreichend) Jetzt selbst kostenlos testen: http://www.gmx.net
